VSE Blender (editing formats native RAW, XAVC, ProRes, cinemaDNG)
Blender VSE is not a time-based video editor (like Premier Pro or Sony Vegas is), but it is a frame-based video editor (like After FX or Nuke).

As such it caches the frames into memory and has no native codec to speak of.

The question which remains is whether it will decode/encode such codecs:


Blender can already read ProRes, ProRes encoder is in development.
There is no support for CinemaDNG. There was a discussion about it and it was suggested it would be better to include the support into the openimageio open-source library directly, rather than into Blender. There was a Google_Summer_Of_Code project wanting to implement DNG but never materialized.
OpenEXR is fully supported


It is generally better to export still frames from Blender and encode the video with different application - for output formats and performance reasons.
